The research team of Professor Lee Jihoon of the Department of Electronic Engineering at Kwangwoon University and Ph.D. researcher Rutuja Mandavkar significantly improved 4-ATP (4-Aminothiophenol) and CV (crystal violet) hybrid surface-enhanced Raman scattering (SERS) responsiveness. To achieve it they applied the metasurface-based silver nanoshell palladium core hybrid particle technology.

Surface-enhanced Raman spectroscopy (SERS) is a superior analysis and detection technology that recognizes and detects molecular substances even at very low molecular weights or molecular concentrations. Surface-enhanced Raman spectroscopy is an advanced analytical technique that can significantly improve the very weak Raman signal of an analyte and has been widely applied in various research fields such as chemical species identification, environmental monitoring, and biosensors, clinical diagnosis, and food safety.
